I have now dedicated two Raspberry Pi to work on some bare metal (C, assembler, no operating system) code. I'm hoping that publishing some of this work will help to start somekind of an effort to get the OpenSolaris ARM code out of the mothballs.
Obviously, long term will be to get the IllumOS kernel booting, but there is a lot of work between now and then.
On this blog
So, usually I post all the Raspberry Pi stuff on the Raspberry Pi Python Adventures blog, but I want to keep it mostly Python, with the occasional C code (swig etc). Since we are going bare metal, I think it'll be better if I track this stuff here.
